You need to post what it is your having trouble with, things you've tried on your own already and what the expected result should be. Posting code alone is not sufficient for understanding your question. Also, next time, please wrap your code in the proper tags.

How about all the information on CODE tags like
1) in the Rules you were asked to read when you registered
2) in the text at the top of this forum
3) in the announcement at the top of this forum titled Please use BB Code and Inlinecode tags
4) in the sticky post above titled Read Me: Read This Before Posting
5) any place CODE tags were used, even in responses to your posts
6) Even on the background of the box you actually typed your message in!

1) Use code tags.
2) #include "blah.h" tells compiler to look into the project directory
for the file. Libraries like string and cctype are not in your directory
and so use #include<blah> syntax.
3) Whats your problem?

this is my program in static record handling... there's so many changes i have done... now i am now trying to update , delete record but i can't delete , update a record... there's something wrong in my program.. actually, it will compile... can you help me in my project??

Dude, you've already been told about code tags and where to use them, AND where to find info about them on the forum. I cant help you if I cant read your code... i.e the messy brackets in your nested loops because of the lack of code tagging

or you can highlight your code in the editing box and click on the

Look at the writing on the background of the Quick Reply box. It's also in the documentation when you first sign up. There's a large bold blue announcement about it in every forum. When you received the notification the first time from the moderator there was documentation in the PM as to how to do it. I had sent you a PM as a courtesy about it.

It's crucial but especially so when you are posting large code samples to have the formatting intact (posting it as plain text strips all the leading spaces and makes a mess).[code]

I don't know how much clearer any of us can make it for you. Go up to the blue background of the code and click on "Help With Code Tags" or click on the dark blue bold announcement on the C++ forum page.
